Description

  The present invention relates to a floor-mounted fixture, a fall prevention device used therefor, and a base unit. Here, furniture such as cabinets and racks (racks) can be mentioned as typical examples of floor-mounted fixtures, but in addition, display devices such as electric (electronic) products such as multifunction machines and refrigerators, goods, etc. Products such as display devices for goods, servers for personal computers, and distribution boards are widely included, which are placed on the floor and that may fall over in the event of an earthquake.

  Many measures have been proposed to prevent the overturning of cabinets in the event of an earthquake. In the fall prevention means, there is a concept to allow the shaking of the cabinets while allowing the degree to be relaxed, and a concept to keep the cabinets from moving independently even if there is an earthquake (the building moves when the earthquake, so the cabinet The idea is that it shakes against the ground, but does not move relative to the building.)

  As an example of the former method, as disclosed in Patent Document 1, there is a seismic isolation device that moves cabinets relative to a floor. On the other hand, as means for preventing the cabinets from moving independently, as disclosed in Patent Document 2, the top surface of the cabinets is connected to the wall of the building with brackets, and disclosed in Patent Document 3 As described above, there is a table on which cabinets are mounted, provided with forward facing anti-fall plates (outriggers) projecting to the front of the cabinet. As a modification of Patent Document 3, Patent Document 4 discloses that the overturn preventing plate is disposed inside the access floor.

JP, 2016-2420, A Japanese Patent Application Publication No. 2007-37990 Japanese Utility Model Publication No. 4-24990 Patent No. 3541362

  Although the means of Patent Document 1 is considered to be theoretically superior, there is a problem that the structure becomes extremely complicated. On the other hand, although the means of Patent Document 2 is simple in structure, there is a problem that the mounting of the brackets becomes troublesome when the height of the cabinet is high.

  Further, in the case of Patent Document 3, since the outrigger projects largely to the front of the cabinet, there is a problem that people easily get stuck or the appearance is deteriorated (the height of the outrigger portion is high even if covered with carpets) Problems have not been resolved.). Although the fall prevention board can be incorporated in the access floor as in Patent Document 4, the problems of stumbling and aesthetics can be solved, but it takes a lot of time and effort in construction and can not be applied to floors other than the access floor, resulting in poor versatility. There is such a problem.

  The present invention has been made under such circumstances, and an object of the present invention is to provide a vibration control technique which is simple in construction, easy in construction, and excellent in practicality and versatility.

And a second joint fixed to a floor or wall or other fixture to prevent horizontal movement of the horizontal part during an earthquake. "
It has the composition.

In the invention of claim 10, the fixture is specified. That is, this fixture is
"Having a fall prevention device according to any one of claims 1 to 9"
It has the composition.

  In addition, in this invention, it does not exclude that furniture has other functions, such as a shock absorbing device other than a fall prevention device. It is preferable as a countermeasure against earthquakes in furniture to have a device for assisting the fall prevention device.

  When an upright piece is provided as the second joint in the horizontal portion, a fixed type partition may be mentioned as an example of the wall as a suitable target for fixing the upright piece. The lower frame (cardboard, ground rail) of the fixed partition is generally made of metal, and self-drilling screws such as drill screws and tapping screws can be used to easily fix the upright pieces. When the fixtures such as the cabinet are arranged back to back, the upright pieces provided on the horizontal portion may be fixed to the rear surface of one fixture. In this case, the rear face of one horizontal part constitutes a wall.

  In the inventions of the present application, the fall prevention device has a simple structure made of a plate material, and installation is also easy. And one of the characteristics of each invention of this application is that the horizontal part which constitutes a fall prevention device is fixed to a floor or a wall, and, for this reason, a horizontal part does not protrude outside the fixture like Claim 3. Even if it is structured, it can prevent falling. Therefore, it is possible to prevent the appearance of the horizontal part from being exposed to the eyes and deteriorating the appearance or the appearance of people, and it is excellent in practicality and versatility.

  If a standup piece is provided as the second joint and the standup piece is fixed to the wall as in the second aspect, the fall prevention device does not necessarily have to be fixed to the floor. Does not get worse and can be applied without problems to floors that can not be anchored, such as carpeted floors. Also in this aspect, it is excellent in practicality and versatility.

  In addition, when the upright piece is fixed to the wall, the entire horizontal portion can be bent in the vertical direction so as to be deformed, so that the function of deforming in accordance with the swing of the fixture can be remarkably improved. As a result, it is possible to prevent an excessive load from being applied to the joint portion between the rising piece and the wall, and to hold the fixed state of the overturn preventing device to ensure the overturn preventing effect. Therefore, as in claim 2, it is preferable to configure the fall prevention device with the horizontal portion and the upright pieces in order to obtain a high fall prevention effect.

  According to the third aspect of the present invention, as described above, the horizontal portion can be prevented from being exposed to the naked eye to deteriorate the appearance or the appearance of people, so that the practicality and versatility is excellent.

  In the case of an earthquake, the fixtures tend to shake against the building, so a large moment may act on the fixed points of the uprights. In this respect, according to the fourth aspect of the invention, as described above, since the kinetic energy of the fixture is absorbed by the horizontal part being deformed while being moved relative to the fixture, the moment acting on the fixed part of the upright piece Can be suppressed to improve the fall prevention performance. In addition, the property which a horizontal part deform | transforms, moving relative to a fixture at the time of an earthquake can be ensured by making a fall prevention apparatus into metal plates like a steel plate or a stainless steel plate.

  Fasteners such as screws can also be used as a means for joining the horizontal portion and the fixture, but when an adhesive sheet or adhesive is used as described in claim 5, the horizontal portion and the furniture separate or adhere It is possible to significantly reduce the vibration of the fixture acting on the fixed part of the upright piece. Therefore, the fall prevention device can be prevented from being detached from the building or the like, and the fall prevention function can be improved.

  The pressure-sensitive adhesive sheet in claim 5 means a sheet which is thin in advance and attached to the overturn prevention device, and the adhesive is applied to the horizontal portion of the overturn prevention device in an irregular state. It means something. In addition, the pressure-sensitive adhesive sheet includes both a single-layer structure entirely composed of a pressure-sensitive adhesive and a multilayer structure in which a pressure-sensitive adhesive layer is provided on both upper and lower surfaces of a film or sheet such as resin.

  According to the sixth aspect of the present invention, the ground body such as the adjuster bolt is connected to the horizontal portion, but the connected state can be reliably held by a member made of metal or the like, so that the durability is excellent. Further, since the assembly can be performed using a screw (bolt), the assembly can be easily performed and the stability of the quality is also excellent. Furthermore, cost reduction is also possible compared with the case where an adhesive material is used.

  There are two types of partitions: the upper end is connected to the ceiling and the upper type does not reach to the ceiling (row partition), and box type furniture such as cabinet is often arranged on the wall of the upper partition. It is The problem in this case is that the partition itself may be offset during an earthquake since the partition is only standing and standing on the floor.

  In this respect, when the auxiliary plate is provided as in the seventh aspect, the upright pieces and the partition can be fixed to the floor through the auxiliary plate, so that lateral displacement of the partition can be prevented, and a high overturn preventing effect can be secured. . Further, when the auxiliary plate is provided as in the seventh aspect, the horizontal portion can be held on the floor so as not to be displaced horizontally via the auxiliary plate, even if the horizontal portion is not fixed to the partition wall etc. Even if the fixtures are not placed on the wall, they can contribute to the prevention of falling of the horizontal part.

  The office floor is often a double floor (access floor) with floor panels laid on a concrete slab, but when the floor panels are made of metal plate (steel plate), the auxiliary plate It is preferable because it can be fixed easily and firmly with fasteners such as drill screws, tapping screws, and expandable blind anchors. Combinations of blind nuts and screws can also be employed.

  The double floor is constructed for the purpose of wiring cables in the hollow part, and cables such as the power supply cable, LAN cable and telephone line are laid on the floor slab, and the holes and holes provided in the floor panel It is pulled out on the floor from the gap. In this case, the cable may be drawn into the interior of the cabinet or the like, but it is not preferable that the fall prevention device inhibits the cable from being pulled out.

  In this respect, when the configuration of claim 8 is adopted, the cable can be drawn out of the window hole or the notch to the inside of the fixture, so that the cable can be prevented from being exposed to the outside of the fixture and the cable can be beautifully treated it can. The window hole and the notch may be provided side by side. The formation of the notched portion at the outer periphery has an advantage that the cable can be wired without being removed from the device even if a large device is connected to the cable.

  Now, for example, a horizontally long cabinet shakes in the front and back direction during an earthquake, but due to the relationship between the attitude of the cabinet and the shaking direction of the earthquake, the center of gravity of the articles stored in the cabinet, etc. It can be seen that it swings in a twisted attitude (horizontally turned attitude). Then, when it shakes in a twisted state in plan view, the front corner portion acts as if it is stretched on the floor, and the cabinet is less likely to tip over.

  Therefore, it can be said that the overturning prevention effect is enhanced if it is promoted that the fixtures such as the cabinet and the like shake in a twisted posture in plan view, but if a hole and a notch are provided in the horizontal portion as in claim 8, the horizontal portion is twisted Since it becomes easy to deform, it is easy to shake the fixture in a twisted posture in plan view, and it can be said that the fall prevention effect can be improved.

  Since box-type furniture such as a cabinet often has a form in which the main body is mounted on the base, when the unit is configured of the base and the overturn prevention device as in claim 9, the furniture main body has a conventional configuration. Because it is good, it has excellent versatility. It is also excellent in that it can be applied to existing furniture as it is. As described in claim 10, incorporating a fall prevention device or a base unit in a fixture can greatly improve the value of furniture.

(1) Outline of First Embodiment Next, an embodiment of the present invention will be described based on the drawings. First, a first embodiment shown in FIGS. 1 to 5 will be described. This embodiment is applied to the fall prevention of the steel cabinet 1 formed in the rectangle long in plan view.

  The cabinet 1 includes a cabinet body 2 opened forward, a horizontally pivotable double door 3 for opening and closing the opening, and a steel plate base 4 on which the cabinet body 2 is mounted. The rear surface (rear surface) of the cabinet 1 is disposed on the outer surface of (or closely attached to) the outer surface of the fixed partition 5 as an example of indoor equipment, but the cabinet 1 has a depth much smaller than the height. , It is easy to fall to the front in case of an earthquake. Therefore, the overturn prevention device 6 is used.

  The overturn preventing device (overturn preventing plate) 6 is made of steel plate and has a horizontal portion 7 located below the base 4 and an upright piece 8 rising from the rear end edge of the horizontal portion 7. Is fixed to a lower frame (a base wood, a ground rail, a runner) 9 in a horizontal posture that constitutes the lower end of the partition 5 with a screw 10. A plurality of mounting holes 11 are formed intermittently in the horizontal direction in the upright piece 8.

  The partition 5 of the embodiment has a structure in which the panel 13 is mounted on the front and back of a framework consisting of left and right vertical frames 12, lower frames 9 and upper frames (not shown), and the vertical frames 12 are brought into contact with the ceiling. It has a fixed structure. The lower frame 9 may be fixed to the floor or may simply be on the floor.

  The front-rear thickness of the lower frame 9 is smaller than the entire thickness of the partition 5. That is, the front and rear surfaces of the lower frame 9 are inward in the thickness direction than the front and rear outer surfaces of the panel 13. Accordingly, the rising pieces 8 of the fall prevention device 6 enter the inside from the outer surface of the panel 13. For this reason, the rear end of the horizontal portion 7 protrudes behind the front of the cabinet 1.

  When the overturn preventing device 6 is not attached, it is also possible to attach the left and right long cover plates to the lower frame 9. When the front surface of the lower frame 9 is flush with the front surface of the panel 13 or when the upright piece 8 is fixed to the front surface of the panel 13, the horizontal portion 7 may extend beyond the rear surface of the cabinet 1. Absent. Furthermore, the back surface of the base 4 may be slightly shifted to the front side of the back surface of the cabinet body 2. In this case, even when the rising piece 8 is fixed to the panel 13, the rising piece 8 is a cabinet in plan view The rear surface of the cabinet main body 2 can be superimposed on the front surface of the panel 13 because it can be shifted to the front side than the rear surface of the main body 2.

  The horizontal portion 7 of the overturn prevention device 6 has a size substantially overlapping with the cabinet 1 in a plan view, and neither the front end nor the left or right side end protrudes outside the cabinet 1 (outside of the base 4) in a plan view. And the adhesive sheet 14 as an example of the 1st joined part indicated to the claim is stuck on the field of the right-and-left both sides among horizontal parts 7. As shown in FIG. Or it is also possible that the site | part of the right-and-left both sides among the horizontal parts 7 becomes the 1st junction part connected with the base 4 through the adhesive sheet 14. As shown in FIG. The pressure-sensitive adhesive sheet 14 is formed in a rectangular shape in the front and back direction.

(2) Details of Base Unit As shown in FIGS. 2 and 3, the basic structure of the base 4 is the same as that of the prior art, and the left and right side frames 16 and the front frame 17 and rear frame 18 connecting these are connected. Each of the frames 16, 17 and 18 is formed in a grooved shape having upper and lower horizontal pieces 19 and 20 and vertical pieces 19a and 20a provided at the tips thereof.

  The lower horizontal piece 20 is narrower than the upper horizontal piece 19. The upper horizontal piece 19 of the front frame 17 is wider than the upper horizontal piece 19 of the rear frame 18, but both may have the same width.

  As shown in FIGS. 2 and 3, the front and rear auxiliary frames 21 are disposed on the left and right sides of the base 4. The auxiliary frame 21 is in the form of a U-shaped opening upward, and the front and rear ends thereof are fixed to the front frame 17 and the rear frame 18 by welding or the like.

  As clearly shown in FIGS. 2B and 3B, the lower end of the auxiliary frame 21 is located above the lower end of the base 4, and the front and rear ends of the auxiliary frame 21 are described in the claims. As an example of the first joint portion, left and right long connecting members 22 are fixed by an adjuster bolt 23 via a nut plate. Then, the receiving plate 24 is fixed to the lower surface of the connecting member 22 with a bolt 25. The connecting member 22 is in the form of a substantially M shape in a front view having flaps projecting to the left and right sides of the auxiliary frame 21, and the flaps on the left and right are fixed to the receiving plate 24 by bolts 25.

  In addition, it is also possible to make the front and rear connection members 22 continuous in series. Alternatively, the receiving plate 24 may be directly fixed to the auxiliary frame 21 without using the adjuster bolt 23 and the connecting member 22. When the receiving plate 24 is directly fixed to the auxiliary frame 21, one receiving plate 24 may be fixed to one auxiliary frame 21, or one receiving plate 24 may be fixed to two auxiliary frames 21. May be

  Although the receiving plate 24 is separated to the left and right, it is also possible to make a single plate type continuously in series, or to make three types of left and right and center. It is also possible to fix the receiving plate 24 to the lower horizontal piece 20 of the base 4. When the adjuster bolt 23 is provided, it is also possible to use the receiving plate 24 as a connecting member.

  Although the receiving plate 24 is located below the base 4 in the figure, the receiving plate 24 can be inserted into the base 4 by raising the height of the lower surface of the auxiliary frame 21 or the like. In this case, the appearance of the cabinet 1 is good because the gap between the base 4 and the floor can be made as small as possible.

  The receiving plate 24 has substantially the same size as the pressure-sensitive adhesive sheet 14, and is set such that the entire lower surface of the receiving plate 24 overlaps the pressure-sensitive adhesive sheet 14. The receiving plate 24 is made of a steel plate thicker than the material plate of the base 4 and has rigidity not to be deformed (elastically and plastically deformed) even if the cabinet 1 shakes in the event of an earthquake.

  The pressure-sensitive adhesive sheet 14 is only required to ensure the necessary adhesion, and therefore, the composition is not particularly limited, but it is desirable that the adhesion be as high as possible. Moreover, adhesion is generally defined as peeling off when a peeling force exceeding the limit acts, and sticking again if pressure is released, but the adhesive sheet 14 of this embodiment is also peeled off and re-adhered. Is possible.

(3) Summary of the First Embodiment FIG. 4 shows an example of the construction procedure. First, the overturn preventing device 6 is disposed at a predetermined position, and the upright piece 8 is fixed to the lower frame 9 of the partition 5 with the screw 10. As the screw 10, for example, a drill screw or a tapping screw can be used. It is also possible to make a tap hole in advance in the lower frame 9 (in this case, the mounting holes 11 of the upright pieces 8 are formed in the left and right long oblong holes so that the left and right positions of the overturn preventing device 6 can be adjusted). Is preferred)).

  Next, the adhesive sheet 14 is attached to a predetermined position of the horizontal portion 7. It is needless to say that the release sheet is stuck on the front and back of the adhesive sheet 14 and one of the release sheets is peeled off and then stuck on the upper surface of the horizontal portion 7. In order to stick the adhesive sheet 14 at an accurate position, the horizontal portion 7 may be provided with a display line (enclosed line) or the like indicating the sticking position. The pressure-sensitive adhesive sheet 14 can be attached to the overturn prevention device 6 in advance.

  The cabinet 1 is then placed on the horizontal part 7. In this case, first, the base 4 is placed on the horizontal portion 7, and then the cabinet body 2 is fitted into the base 4, and the base 4 is assembled in advance to the cabinet body 2. There is a method of stacking and placing on top of, but any of them can be adopted.

  In the case where the base 4 is disposed first, it is necessary to accurately set the position of the base 4 so that the cabinet body 2 exactly overlaps the outer surface of the partition 5. In this regard, the base 4 may be arranged with a cage of a predetermined thickness with the lower frame 9 or the like. If the height of the base 4 is higher than that of the lower frame 9, placing the back of the base 4 in contact with the surface of the partition 5 has the advantage of accurate positioning.

  The cabinet body 2 has a bottom plate 2a, and the bottom plate 2a is provided with a downward piece 2c which enters the inside of the base 4. The cabinet body 2 may only have the downward piece 2c fitted in the base 4 or the bottom plate 2a may be fixed to the base 4 with a screw.

  Since there is space between the base 4 and the lower frame 9, the head of the screw 10 does not hit the rear surface of the base 4. Therefore, the screw 10 can use the thing of a pan head and a hex head other than a flat head. Instead of fixing the screw 10 directly, it is also possible to fix a blind nut to the lower frame 9 and screw a screw into this blind nut. Alternatively, it is possible to make a lower hole in the lower frame 9 and insert a blind anchor having an extended portion by using the lower hole, and tighten the upright piece 8 and the lower frame 9 together by the blind anchor. It is.

  FIG. 5 shows the swinging movement of the cabinet 1 and the deformation of the horizontal portion 7 in the event of an earthquake. The cabinet 1 swings back and forth due to the swing of the floor surface, but since the rear surface hits the partition 5, it swings generally between the vertical posture and the forward lean posture as shown by the alternate long and short dash line and solid line in FIG. There is.

  And since the rising piece 8 is being fixed to the lower frame 9 of the partition 5, the fall prevention apparatus 6 will deform | transform into a chevron so that the horizontal part 7 may bend upwards, when it falls to the front, The adhesive sheet 14 is peeled off from the base 4 at the location of the above, and when the cabinet 1 is tilted forward to some extent, the elastic restoring force of the horizontal portion 7 wins, and the receiving plate 24 rotates back (in addition, the horizontal portion 7 is plastic) It is possible to deform.).

  Since the cabinet 1 collides with the partition 5 when it pivots back, as shown in FIG. 5 (B), a phenomenon that the cabinet 1 is slightly inclined backward is seen, but in this state, the horizontal part 7 is from the floor Backward tilting is permitted by the fact that the angle between the receiving plate 24 and the rising piece 8 is increased in the floating state.

  From these things, in the present embodiment, the deformation of the fall prevention device 6 is closely related to the swing of the cabinet 1, and the elastic restoring force that returns after the deformation of the horizontal portion 7 causes the shake of the cabinet 1. It can be understood that it contributes significantly to reducing. In addition, even if the cabinet 1 and the horizontal portion 7 are partially peeled off, the bonding state is maintained without completely coming off.

  Therefore, it is possible to prevent the rising pieces 8 from being separated from the lower frame 9 while preventing the kinetic energy of the cabinet 1 from acting intensively on the rising pieces 8. The adhesion of the adhesive sheet 14 is preferably as large as possible. The deformation of the horizontal portion 7 also prevents an excessive moment from acting on the fastening portion between the upright piece 8 and the lower frame 9.

(4) Second to Sixth Embodiments FIG. 6 shows another embodiment. Among them, in the second embodiment shown in (A), the overturn preventing device 6 corresponding to one cabinet 1 is separated left and right. When the separation method is adopted in this way, there is an advantage that furniture of different width can be handled by one type of fall prevention device 6.

  In the third embodiment shown in (B), contrary to the second embodiment, a plurality of cabinets 1 are supported by one fall prevention device 6. In this embodiment, there is an advantage that the fronts of the cabinets 1 arranged side by side can be exactly aligned.

  In the fourth embodiment shown in (C) (D), only the front portion of the receiving plate 24 is fixed to the horizontal portion 7 of the overturn preventing device 6 by the bolt 26 and the nut 27 ((D) is an example of (C) It is a principal part enlarged view.). The bolt 26 has a countersunk head 26a, and the horizontal portion 7 is formed with an upward projecting portion 28 in which the countersunk head 26a fits from below, and the countersink 26a is welded to the upward projecting portion 28 It is fixed by. On the other hand, the receiving plate 24 is formed with a tapered recess 29 into which the upward projection 28 of the horizontal portion 7 enters.

  Also in this embodiment, in the event of an earthquake, the rocking movement of the cabinet 1 and the elastic deformation of the horizontal part 7 occur simultaneously while holding the joined state of the horizontal part 7 and the receiving plate 24, so that the rocking of the cabinet 1 can be suppressed. .

  As shown in (E) as a sixth embodiment, it is also possible to connect the horizontal portion 7 and the receiving plate 24 via an elastic body 30 such as rubber. In this embodiment, even if the horizontal portion 7 and the receiving plate 24 are connected at a plurality of front and rear positions, the shaking of the cabinet 1 and the deformation of the horizontal portion 7 are allowed. Therefore, the stability is excellent. In the fifth and sixth embodiments, as a construction procedure, first, the base 4 is disposed, and then the cabinet body 2 is placed on the base 4.

(5) Outline of Seventh Embodiment (FIGS. 7 to 12) Next, a seventh embodiment will be described. The basic aspect of this embodiment is the same as that of the first embodiment. The same elements as in the first embodiment are denoted by the same reference numerals, and descriptions thereof will be omitted unless necessary.

  For example, as shown in FIG. 12, nut cylinders 32 are fixed to the front and rear end portions of the auxiliary frame 21 and height adjusting adjuster bolts 23 are screwed into the nut cylinders 32 from below as an example of a grounding body.

  As clearly shown in FIG. 9, at the four corners of the horizontal portion 7 in the overturning prevention device, as a component of the first joint, a laterally long fixing bracket 33 made of steel plate is fixed by welding. As shown in FIG. 12, an inverted M-shaped connecting member 22 is fixed to the fixing bracket 33 by a bolt 34 (see FIG. 12). Accordingly, as shown in FIG. 9A, for example, the fixing fitting 33 has a tap hole 35 for fixing the connecting member 22.

  A protrusion 33 a is formed forward on the front fixing bracket 33, and a rear facing protrusion 33 a is formed on the rear fixing bracket 33. The protrusion 33 a is provided for stably mounting the adjuster bolt 23. That is, in order to support the cabinet 1 stably, it is preferable to arrange the adjuster bolt 23 as close to the outer periphery of the base 4 as possible. However, when the fixing bracket 33 is a mere square, the front and rear width of the fixing bracket 33 is large. Then, there is a possibility that the horizontal portion 7 is unlikely to be deformed. Therefore, in order to support the adjuster bolt 23 stably while minimizing the area of the fixing bracket 33, the protrusion 33a is provided.

  Moreover, although the fixing metal fitting 33 is provided with a pair of front and rear tap holes 35, this is for adapting it to the type of wall of the partition 5 and the like. That is, as shown in FIG. 8, when applied to the partition 5 provided with the lower frame 9 which is recessed from the wall surface, the connecting plate 22 is fixed using the tap hole 35 on the front side. As described above, when the upright piece 8 is fixed to the wall surface of the partition 5 or the like, the connecting plate 22 is fixed to the rear tap hole 35. Therefore, one type of fall prevention device can be shared by a partition provided with the lower frame and a partition not provided with the lower frame.

  The adjuster bolt 23 is inserted into the upward bulging portion of the connecting member 22 from below. From a different point of view, in order to form an arrangement space for the head of the adjuster bolt 23, the connecting member 22 is formed with an upward bulging portion. The base 4 is connected to the horizontal portion 7 in an inseparable manner via the connecting member 22 and the adjuster bolt 23. When the adjuster bolt 23 is rotated, the height of the base 4 can be adjusted.

  It should be noted that a spring washer or rubber ring overlapping the seating surface is fitted into the adjuster bolt 23 so that the head of the adjuster bolt 23 does not rattle between the fixing bracket 33 and the connecting member 22 in the event of earthquakes. It is also possible to hold

  In this embodiment, the horizontal portion 7 is formed with a cut-away portion 36 which opens forward. Although the cut-away portion 36 is formed at the left and right middle portions, it may be formed at a plurality of left and right portions. Although the depth (depth) of the cut-away portion 36 is about 1⁄3 of the depth dimension of the horizontal portion 7, both the lateral width and the depth can be set arbitrarily. It is also possible to form in a state of being opened backwards.

  By forming the cutout 36, the cable pulled out from the inside of the double floor can be pulled out to the inside of the cabinet 1 without being exposed to the outside. In addition, since the horizontal portion 7 is easily torsionally deformed, there is an advantage that breakage of the horizontal portion 7 can be prevented. As shown in FIG. 9A, in place of or in addition to the cut-away portion 36, the cables can also be pulled out by opening a window hole 38 such as a circular shape. It is also possible to form a plurality of cutouts 37 on the left and right.

  In this embodiment, as shown in FIG. 7, a buffer body 41 is used in the upper portion of the cabinet body 2 and the elastic body 40 is fixed to the rear surface of the L-shaped plate 39 overlapping the upper surface and the rear surface of the cabinet body 2. The elastic body 40 is made of a material having appropriate elasticity, such as a synthetic resin or an elastomer, is formed in a forward opening U shape, and is fixed to the rear surface of the L-shaped plate 39. The buffer 41 has a kind of hollow structure.

  In the case of an earthquake, the cabinet 1 may rotate back and collide with the partition 5 violently, but if the buffer body 41 is provided as in the embodiment, breakage and deformation of the partition 5 can be prevented. In addition, since the upper end of the cabinet body 2 is supported by the partition 5 via the buffer body 41, it is possible to prevent the cabinet 1 from vibrating due to the backward movement of the drawer or the like.

  Furthermore, the upper end of the partition 5 is fixed or locked to the ceiling surface via a ceiling rail or the like, and if the ceiling has a lightweight structure in which the panel is simply mounted on the lightweight frame, the ceiling 5 will receive a large impact If the shock absorber 41 is provided as in the present embodiment, the shock can be mitigated even when the cabinet body 1 is turned back and turned against the partition 5 in the event of an earthquake, so the damage and deformation of the ceiling It is also possible to prevent

  The operation at the time of the earthquake is the same as that of the first embodiment, and even if the cabinet 1 swings back and forth, the overturn preventing device 6 can prevent the falling down. In this case, the horizontal portion 7 of the overturn preventing device 6 is deformed as shown in FIG. 5A to allow the swing of the cabinet 1, but as described above, since the notch portion 36 exists, the horizontal portion 7 is in a state easy to deform. As a result, the elastic restoring force generated in the horizontal portion 7 can be reduced, and the cabinet body 2 can be prevented from violently colliding with the partition 5 due to the return rotation.

  Now, when observing the shaking of the cabinet 1 in the reproduction experiment of the earthquake, as shown in FIG. 19 (A), the horizontal turning in plan view is performed because the position of the center of gravity is shifted left and right or back and forth from the center. The phenomenon of swinging back and forth while twisting to the attitude (horizontal rotation) can be seen. Since the front corner portion 2a of the cabinet 1 comes out before the normal position when it is in such a twisted posture (to be precise, the front adjuster bolt 23 is shifted before the normal position), the cabinet 1 falls over. It becomes difficult to do.

  Then, when the notch 36 is formed as in the seventh embodiment, the horizontal portion 7 of the overturn preventing device 6 is also easily torsionally deformed, and the cabinet 1 is likely to be in a twisted posture in plan view. It can be said that the effect can be improved.

(6) Eighth embodiment (FIGS. 13 and 14)
In the eighth embodiment shown in FIGS. 13 and 14, the cabinet 1 is fixed to the partition 5 of the screen type. That is, the cabinet 1 is disposed along the front surface of the partition 5. The partition 5 includes a hollow lower frame 43, and an adjuster bolt 44 is screwed into the lower frame 43 at a lower position.

  On the other hand, the rear portion of the overturn prevention device 6 is provided with a rear auxiliary plate 45 fixed to the floor surface with a screw (screw) 46, and a rear wall plate 45a is bent at the rear end of the rear auxiliary plate 45. The wall plate 45 a and the upright piece 8 of the overturn preventing device 6 are fastened together with the screw 10 to the rear frame 43 of the partition 5.

  When the partition 5 is a screen type, the partition may shift sideways or move up and down at the time of an earthquake and the fixing function to the cabinet 1 can not be expected, but the auxiliary plate 45 is used as in this embodiment. When the rear wall plate 45a and the rising piece 8 of the overturn prevention device 6 are fastened together to the partition 5, the rising plate 4 is fixed to the floor F via the auxiliary plate 45, and the partition 5 is a reinforcing plate of the rear wall plate 45a. Therefore, the fall prevention effect of the cabinet 1 can be secured.

  In the present embodiment, the rear wall plate 45a of the auxiliary plate 45 also constitutes a wall described in the claims. Therefore, the wall body is constituted by the partition 5 and the rear wall plate 45a. The auxiliary plate 45 is also an example of the second joint portion described in the claims. Therefore, it is possible to view that the overturning preventing device 6 is constituted by the main plate provided with the upright piece 8 and the auxiliary plate 45 provided with the rear wall plate 45a.

  When the partition 5 is not disposed, it is possible to use only the auxiliary plate 45 to prevent the overturning. When the cabinet 1 is arranged in the form of an island on the floor without the partition 5, the rear wall plate 45a of the auxiliary plate 45 is exposed to the outside, but when the rear wall plate 45a is exposed to the human eye, the rear wall plate A cover may be provided to cover 45a from the outside.

  Since the rear auxiliary plate 45 is disposed only at the rear, the horizontal portion 7 of the overturn prevention device 6 is uneven. In this regard, as shown by the alternate long and short dash line in FIG. 13B, the adjusting plate 45 'having the same thickness as the auxiliary plate 45 is fixed to the lower surface of the portion of the horizontal portion 7 where the fixing bracket 33 is located. It is good. However, while the thickness of the auxiliary plate 45 is small, the horizontal portion 7 has a certain longitudinal width, so even if the adjustment plate 45 'is not provided, the step is absorbed by the deformation of the horizontal portion 7 ( The difference in height between front and rear can be adjusted by the adjuster bolt 23.).

  Although the floor panel 47 is drawn as a simple flat plate, it actually has a foot which rests on a concrete slab. Also, the periphery is bent downward to increase rigidity. Although the floor panel 47 of the embodiment is made of steel, one made of concrete or synthetic resin can also be adopted. The auxiliary plate 45 can be fixed to the steel floor panel 47 by a tapping screw or a drill screw. It may be fixed using the blind anchor described above, in which case much higher fastening strength can be obtained compared to using screw-on fasteners.

(7). Ninth to tenth embodiments (FIG. 15)
In the ninth embodiment shown in FIG. 15 (A), two cabinets 1 are arranged in a back-to-back manner, and an anti-falling device 6 having upright pieces 8 is connected to the bases 4 of both. The rear parts of the two overturn prevention devices 6 are attached to the wall plate 45a erected from the auxiliary plate 45 which has entered the lower part of the two bases 4 in the same manner as shown in FIG. It is tightened at 49.

  Therefore, in this embodiment, the auxiliary plate 45 is an inverted T-shape having a wall plate 45a at the front and rear middle portion, and only the wall plate 45a functions as a wall body recited in the claims. The auxiliary plate 45 is fixed to the floor surface F by screws 46 below the two cabinets 1 in the same manner as shown in FIGS. In this embodiment, since the two cabinets 1 are connected via the auxiliary plate 45, the stability of the cabinet 1 can be remarkably improved. When the upper ends of the cabinets 1 adjacent to each other in the front and rear direction are connected by a joint member (shown), the overturn preventing effect is remarkably enhanced.

  Instead of using the reverse T-shaped auxiliary body 45, two L-shaped auxiliary plates 45 used in FIG. 13 may be used to arrange them back-to-back (both are welded or screwed It may be fixed or integrated. .

  In the tenth embodiment shown in FIG. 15 (B), the cabinets 1 are independently arranged in an island shape, and the overturning prevention device 6 has a form in which rising pieces 8 are provided in front of and behind the horizontal portion 7. There is. Therefore, the fall prevention device is in the form of an upward opening U in a side view. In this embodiment, the auxiliary plate 45 is disposed below the front and rear portions of the overturn preventing device 6, and the wall plates 45 are provided on the front and rear auxiliary plates 45. The wall plate 45 b of the auxiliary plate 45 and the upright piece 8 of the overturn preventing device 6 are fixed by screws 48 and a nut 49.

  In this embodiment, since the cabinets 1 are independently disposed in an island shape, in the event of an earthquake, the cabinet 1 swings back and forth across the reference posture. Therefore, the horizontal portion 7 of the overturn preventing device 6 is deformed in such a manner that the bent state of FIG. 5 (A) appears alternately in the left and right directions.

  In this manner, the anti-rollover device in which the standup pieces 8 are provided at two positions in front of and behind the horizontal portion 7 is arranged back to back so that the standup pieces overlap back and forth. The upright pieces may be connected by a fastener such as a screw. According to this structure, since the cabinets are regulated against falling down, it is possible to exhibit a high rolling prevention effect even if there is no partition wall or the like.

  The auxiliary plate 45 is fixed to the floor surface F by the screw 46. However, as shown in FIG. 15C, the horizontal portion 7 of the overturn preventing device 6 has a relief hole 50 for exposing the head of the screw 46. There is. In this embodiment, the cabinet 1 can be prevented from falling forward or backward. Therefore, even if the cabinets 1 are arranged independently in an island shape, a high fall prevention effect is exhibited. In addition, it is also possible to make the auxiliary | assistant board 45 continuous in series, and to comprise an auxiliary board into one sheet.

(8). The eleventh to thirteenth embodiments (FIG. 16)
The eleventh embodiment shown in FIG. 16 is a modification of the embodiment shown in FIG. That is, in this embodiment, when the wall plates 45a are provided at the front and rear ends of the auxiliary plate 45, the front and rear wall plates 45a are integrally provided on the upright piece 8. That is, using a single metal plate (steel plate), the auxiliary plate 45 is formed integrally with the overturn preventing device 6. In this embodiment, the step of fixing the upright piece 8 and the wall 45a is unnecessary, so that the construction is easy.

  The twelfth embodiment shown in FIG. 16B is a modification of the eleventh embodiment. That is, in this embodiment, in the case where the rising piece 8 of the fall prevention device 6 and the wall plate 45a of the auxiliary plate 45 are integrally continued, a portion on the upper side is formed as the overlapping portion 51 overlapping exactly. In the lower part of the area, the two are spaced apart. Therefore, the horizontal portion 7 of the overturn preventing device 6 is easily deformed. The polymerization part 51 may be simply folded or fixed by spot welding.

  The thirteenth embodiment shown in FIG. 16C uses a blind anchor 51 as a fixing means. In this embodiment, the blind anchor 51 is used to fix the upright piece 8 of the overturn preventing device 6 to the rear frame 9 of the partition 5. The blind anchor 51 is widely known and has a cylindrical body 53 having a flange head 52 and a screw 54 screwed into the cylindrical body 53, and is formed on the cylindrical body 53 by screwing in the screw 54. The expanded portion 55 spreads and deforms inside the rear frame 9.

  As described above, when the expandable blind anchor 55 is used as the fastening means for the members, even the thin plates can be fastened with extremely high strength, so that it can be said that the high overturn preventing effect is exhibited. Also, as described above, it is also excellent in that it can be fixed with high strength to concrete floor panels.

(9) Fourteenth to nineteenth embodiments (FIGS. 17 to 19)
In the fourteenth embodiment shown in FIG. 17, the cabinet 1 is fixed to the LGS wall 58. That is, the LGS wall 58 is composed of a runner 59 with an upward opening C-shape fixed to the floor F with a screw or the like, a group of many lightweight steel 60 supported inside the runner 59, and a lightweight steel 60 It is provided with panels 61 such as a gypsum board etc. which were stretched by the frame, and is used abundantly for the partition between rooms, etc. The lightweight mold steel 60 is shown as a hollow square in the drawing, but a channel material having a C-shaped cross section is also widely used.

  The upright piece 8 of the overturn preventing device 6 is screwed into the runner 59 through the panel 61. Since the LGS wall 58 is light in weight and low in strength, when the auxiliary plate 45 is used in combination as in the embodiment of FIG. 13, breakage and deformation of the LGS wall 58 can be prevented and a high fall prevention effect can be exhibited.

  In FIG. 17, the state in which the LGS wall 58 is erected on the floor surface F is displayed, but in the case of a double floor, the runner 59 is fixed to the floor slab G as shown in FIG. Are normally hidden beneath the floor panel 47, so when placing the cabinet 1 on a double floor floor, the standup pieces 8 of the anti-falling device 6 are studs via the panel 61 It needs to be fixed at 60.

  In this case, since the arrangement pitch of the studs 60 is quite large, in the case of fastening with only one screw, an excessive load may be applied to one screw when the earthquake shakes, and the screw may be pulled out of the stud 60 There is. Therefore, in the fifteenth embodiment shown in FIG. 18, the upright piece 8 is fixed to the stud 60 with a plurality of screws, and in this case, the attachment hole 11a is fixed to the upright piece 8 as a means for facilitating the construction. A large number of upper and lower portions 11 b are formed in two upper and lower stages (a plurality of stages).

  That is, the left and right pitches of the mounting holes 11a and 11b are set so that at least three mounting holes 11a and 11b at the top and bottom overlap the width of the stat 60, and the upper mounting holes 11a and the lower mounting holes The groups of 11a and 11b are arranged in a staggered manner so as to be laterally shifted. With such a configuration, the standup piece 7 can be fixed with a plurality of screws regardless of where the stud 60 is located.

  In the embodiment, the six attachment holes 11a and 11b overlap the vertical frame 60. However, when the inventors of the present invention experimented, it was possible to secure the necessary fastening strength if fixed by three screws. Although the places where the screws are arranged are displayed in black, they may be fixed at other plural places.

  In the embodiment, in the lower mounting holes 11a and 11b, a perfect circular mounting hole 11a and a horizontally long long mounting hole 11b are formed. In the case of fixing to the lower frame 9 of the partition, the upright pieces 7 can be fixed to the lower frame 9 at a predetermined pitch by using the mounting holes 11 b of the long holes. If the mounting hole 11b is formed into a long hole, the overturning prevention device can be shifted in the left-right direction. Therefore, a screw is first driven into the mounting hole of the long hole and the overturning prevention device 6 is fixed before final fixing. Positioning the anti-falling device 6 can be performed accurately and easily by setting the right and left positions accurately and then fully fastening, and then taking a screw-in procedure at the other mounting holes.

  This fall prevention device 6 can also be used for the partition 5 in which the lower frame 9 is inward of the surface of the panel 13 as shown in FIG. Since the lower frame 9 is strong in strength, for example, when the cabinet 1 has a width of 900 mm, the required strength can be secured with a total of about 6 screws for each of the three left and right ones. Therefore, the mounting holes 11b of the elongated holes are formed at a pitch P of 100 mm from the left and right middle to the left and right both sides. That is, as described above, the mounting holes 11 b of the elongated holes are formed at the predetermined pitch P as a guide for selecting the position when fixing to the lower frame 9. In addition, it may be determined on the site in consideration of the plate thickness of the lower frame as to how many screws are to be fastened.

  As already described with reference to FIG. 19 (A), in the event of an earthquake, the cabinet 1 swings back and forth in a twisted attitude (horizontally turned attitude) in plan view, and such a twist is seen The phenomenon can promote the fall prevention effect.

  Therefore, in the sixteenth embodiment shown in FIG. 19B, the horizontal portion 7 can be easily deformed following the twist of the cabinet 1 by forming the rib 62 in the inclined posture on the horizontal portion 7 of the overturn preventing device 6. I am careful to do it. Instead of the ribs 62, slits may be formed. Further, in the left and right middle portions of the horizontal portion 7, a notch portion 36 which opens backward is formed.

  In the seventeenth embodiment shown in FIG. 19 (C), in the structure in which the upright piece 8 at the rear of the overturn preventing device 6 is fixed to the lower frame 9 of the partition 5, the auxiliary plate 45 having the wall plate 45a is provided on the upright piece 8. The auxiliary plate 45 which rides on the floor surface F is formed bent at the front end of the horizontal portion 7.

  The front and rear auxiliary plates 45 are fixed to the floor panel 47 by a blind anchor 55 (in the horizontal portion 7, a relief hole for allowing insertion of the blind anchor 55 is formed). Further, the upright piece 8 and the wall plate 45 a are also fastened to the lower frame 9 by the blind anchor 55.

  In this embodiment, it is said that the extremely high fall prevention effect is exhibited by the fact that the standing pieces 8 have the same double structure, and the front and rear auxiliary plates 45 are fixed to the floor panel 47. I see. Also in this case, as shown in FIG. 7, it is possible to form the notch portion 36 in the horizontal portion 7. The auxiliary plate 45 does not necessarily have to be formed over the entire length of the horizontal portion 7. For example, the arrangement mode can be set arbitrarily, such as forming in only two places on the left and right, only in the left and right middle parts, or in three places on the left and right sides of the left and right middle parts.

  Further, the auxiliary plate 45 can be manufactured as a separate member and fixed by spot welding, instead of being bent and formed in the horizontal portion 7. This point is the same as in the other embodiments provided with the auxiliary plate 45.

  In FIG. 20, the overturn preventing device 6 is not provided with a standing piece, and the horizontal portion 7 is fixed only to the floor F. First, in the eighteenth embodiment shown in (A), a plurality of fastening holes 64 are made in a portion of the horizontal portion 7 sandwiched by the left and right fixing brackets 33, and fixing is performed outside the area provided with the fastening holes 64. In order to allow the portion provided with the fitting 33 to be deformed so as to move upward, a score line 63 is formed.

  Therefore, in the present embodiment, the overturn preventing device is a square steel plate, and the location of the fastening hole 64 is the second joint. The form of the score line 63 can be set arbitrarily. Moreover, it is also possible to replace with the score line 63 and to form a slit. As a fastening means, it is preferable to use an expandable blind anchor or a blind nut.

  In the nineteenth embodiment shown in FIG. 20B, an auxiliary plate 45 is integrally connected to the rear end of the horizontal portion 7 so that the auxiliary plate 63 is fastened with a fastener such as a screw or an expandable blind anchor. It has become. In this embodiment, the second half of the auxiliary plate 45 also deforms in the event of an earthquake.

  In the twentieth embodiment shown in FIG. 20C, the auxiliary plate 45 is configured as a separate member from the horizontal portion 7, and the horizontal portion 7 is fixed to the auxiliary plate 45 by spot welding 65 at the front and rear intermediate portions. There is. Further, the auxiliary plate 45 is fixed to the floor F by an anchor.

  In the examples (A) to (C), since the horizontal portion 7 is fixed to the floor F, it is possible to prevent the falling of the fixture even if it can not be fixed to the wall such as a partition for some reason. Moreover, it is suitable also when arrange | positioning fixtures in island shape. In the example of FIG. 20 (C), the horizontal part 7 is designed to be symmetrical in the front-rear direction, so that it is preferable to apply to the fixtures arranged in an island shape.

  In the twenty-first embodiment shown in FIG. 20 (D), the horizontal portion 7 of the overturn preventing device 6 is held and held on the floor via an elastic cylinder 66. Therefore, the horizontal portion 7 can float or deform by deforming the elastic cylinder 66. Therefore, the movement of the fixture can be permitted to prevent a fall. Since a large load is applied to the fastening portion of the horizontal portion 7 in the floor, in this embodiment, an expansive blind anchor 55 is used as a fastener.

(10) Others Although the embodiments of the present invention have been described above with reference to the drawings, the present invention can be embodied variously in other ways. For example, the target fixtures are not limited to cabinets, and as mentioned in the section of the technical field, electrical and electronic devices, vending machines, refrigerators, commodity display shelves, etc. are also included. Moreover, when fixing to a wall, it is also possible to fix to a concrete wall, and it is also possible to divert the backplate of the fixture made back-to-back as a wall.

  The grounding part of the fixture does not necessarily have to be an adjuster bolt. It may be a downward projection having no height adjustment function. Alternatively, the lower surface of the base may be overlaid on the horizontal portion in a wide area (solid overlay).

  The present invention can be embodied in a fall prevention device for furniture. Therefore, it can be used industrially.
